Battery life performance test – Vista vs. OS X on Macbook Pro and Macbook Air

A thorough review of the new Macbook and Macbook Pro including comparing battery life performance of Vista vs. OS X on the Macbook Pro and Macbook Air. A while ago I started testing the Lenovo X300 with hopes of comparing it to Apple's MacBook Air. The review never saw the light of day but the testing was mostly complete. Obviously the X300 doesn't run OS X, but the MacBook Air can run Windows so I compared battery life between the two under Vista, which yielded some unexpected results.
